ABSTRACT:
Apparatus and method for the manufacture of a fibrous web comprises a distributor for depositing dry wood fibers on a planar section of a linearly movable forming wire. A suction box is disposed to the side of the forming wire opposite the distributor. The distributor and suction box are so cooperatively constructed and arranged as to impart a velocity component to the fibers in the direction of movement of the forming wire, so that the angle of inclination of fiber deposition relative to the moving forming wire is from about 21 degrees to about 30 degrees.
